Competitive landscape
Competing modalities: superconducting qubits (IBM, Google)—faster gates (~50 ns vs ~1 µs), lower connectivity flexibility, dilution-fridge overhead; trapped ions (IonQ, Quantinuum)—higher fidelity, slower clock speed, hard to scale physically; photonic (PsiQuantum, Quix)—room-temp friendly, probabilistic gates. Neutral atoms differentiate on reconfigurability and qubit count scalability without proportional wiring overhead.
